TEMPORARY LOOSE-LEAF BINDER.

Applicationed Gctobcr 8, 1,924. Serial No. 742,452.

To oZZ whom 25 may concer-u.'

Be it known that I, PETER FRANK, a citizen of the United States, residing at New York, in the county of New York and State of New York, have inventedcertain new and useful Improven'ients in` rfemporary Looselieaf Binders, ofvwhich the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to temporary looseleaf binders, and hasparticular reference to an improved means for normally maintaining the inserted leaves in proper position within the binder.

An object of my invention is to provide a temporary loose-leaf binder or ledger in which the several leaves of the book may be quickly and conveniently inserted in or removed from the binder and in which a spring-actuated follower or compressor plate is associated with the transverse binding posts to normally clamp the insertion sheets in proper position. Y

A further object of my invention is to provide a temporary loose-leaf binder in which transverse binding posts pass through spaced apertures at or near the marginal edge of the inserted leaves andgthrough spaced apertures in a suitable follower or compressor plate, and to provide novel means cooperating with said' follower or compressor plate for normally maintaining the saine in contact with the paci; of inserted leaves l f A further object of my invention is to provide an improved bindingpost for binders of the type specified, the said posts containing or housing the tension spring connected to the follower or compressor plate for maintaining the same in proper' clamping position.

A still further object of my invention is to provide a temporary loose-leaf binder of the type specified, which is simple in construction, inexpensive to manufacture, reliable in operation, and strong and durable.

In the accompanying drawing forming a part of this specification, and in which like .numerals are employed to designate like parts throughout the several views Fig. lis a perspective view of one form of temporary loose-leaf binder showingl my vimproved posts and compressor plate applied thereto;

F ig. 2 is an enlarged side elevation on the line 2--2 of l, showing in detailL the construction and operation of the .hollow posts and spring actuated compressor plate;

Fig. 3 is a transverse section on the line 3--3 of Fig. 2;

Fig. it is a fragn'iental plan view on the line 4 4 of Fig. 2.

Referring to the drawings,` wherein for the purpose of illustration, is shown a preferred embodiment of my invention, the numeral -6 designates a one-piece back or cover of leatheror other suitable bookbinding material, ,on the inner' surface of which, at a position near the center thereof, is secured a strip of relatively stiff fabric 7, provided with spaced parallel tucks or guide-ways 8. rlhese tucks or guide-ways 8 are `cut ati/ay at spaced intervals throughout their length tovreceive the apertured ends of the transverse binding posts 9, which are pivotally connected to the cover by the removable fastening rods or pintles 10,.passing through the tucks or guide-ways 8 and through the apertured ends of the said binding posts 9. By this construction, any or all of the leaves may be readily inserted in or removed from the binder, it being only necessary to withdraw one of the fastening rods or pintles lO from the tucks or guide-ways 8 andthe apertured ends of the several binding posts 9, at which time the vpreviously positioned leaves may beinoved olf the binding posts 9, or new leaves inserted thereon. All of the above described construction is old and well known in the art and forms no part yof my present invention. i In the preferred form of my invention, l provide. a novel form of transverse binding` post 9, the said post comprisinga substantially U-shaped member, the upper arms` of which are provided near .their ends with axially alined apertures ll and the lower connecting portion of which is provided with a transverse aperture 12, the fastening rods 10 passing through the said apertures for liiivotally mounting the transverse binding posts 9 to the cover 6in the manner specified iu the preceding paragraph. Near the closed end of the U-shaped binding posts 9 and extending between the spaced arms thereof, I position a transverse pin 13 for -a purpose to be hereinafter speciied. V

lfor clamping the inserted sheets 1% Withing the binder and 'for normally maintaining the pack of sheets in proper position therein, l provide a follower or compressor plate 15, the said follower or compressorl plate comprising a thin sheet ot metal or other suitable material .apertured to pass over the respective arms of the U-shaped lzinding posts clearly shon'n in the ac- 'ompan ving d anfings One end of a coiled tension spring 16 is attached to the transverse pin 13 (previously described) while the opposite end of said spring is attached to that'portion ot the lollovver or compressor plate lying between the spaced arms ot the U-shaped binding post. As a convenient manner ot attaching the end ot the spring 16 to the follower or compressor plate 15, that portion ot the plate lying bet-Ween the spaced arms ot the U-shaped binding posts may be bent downwardly to form an apertured lng` 17 to which the end of the spring may be attached. It desired, I may also employ a second metallic strip 18, provided with suitable spaced apertures for passing entirely over the binding posts 9, it being understood that the pack ot inserted leaves 1i is positioned between this second plate and the spring-actuated follower or comi'iressor plate 15 above described.

1n the operation of my improved device, the spaced arms ot the U-shaped binding posts 9 are inserted through the spaced openings in the compressor plate 15 and the ends ot the spring attached respectively to thc transverse pin 13 and to the apertureo` lng 17. The spaced arms of each U-shaped post are new inserted Within the spaced openings in one of the tucks or guide-Ways S, and the fastening rod is inserted through the tuck or guide-Way S ano. through the alined apertures, 11, thus pivtally mounting the binding posts to the cover 6. The leaves 1t are then placed on the transverse binding posts 9 and as the thickness ot the pack increases7 the compressor plate is gradually forced along die binding posts 9, against the tension of the coil springs 17. Vhen the desired numier ot sheets have been inserted, the second metallic strip 1S is placed on the binding posts; the closed ends of the U-shaped binding posts are positioned Within the spaced openings in the other tuck or guide-Way 8; and the fastening rod or pint-le 10 is inserted through this tuck or guide-Way and through the apertures'lQ in the closed end of the U-shaped posts, and the loose-leaf binder with its inserted sheets is thus secured in assembled relation, with the spring pressed i'olloiver or compressor plate clamping the pack of inserted sheets in proper position vzthin the binder.

It Will thus be seen that I provide a tem porary loose-leaf binder in which the sheets may be readily inserted in or removed trom the binder and in which a spring-actuated tollovver or compressor plate is employed to normally hold the inserted sheets in their proper clamped position. Non spccilically, l have provided a novel toi-1n ot transverse binding post tor binders ot the type specitied, the said posts constituting the housing or casing lfor the tension spring employed for actuating the `lfollon'er or compresser plate.

it is to be understood that the l`orm ot my invention herein shovvn and described is to be taken as prei'erred exaniple ot the same, and that various changes in the shape, size and arrangement ot parts may be rcsorted to Without departing from the spirit ot my invention or the scope ol the suhjoined claims.

Having' thus described my invention what l claim as new and desire to secure b v Letters Patent is i. fr ten'iporarjv loose-leali binder, emprising a back or cover, hollow transverse bin-ling posts pivotallv and detachably moulu ed on said cover, a compressor plate monnied on said binding posts at one side oi' the pack ot' inserted sheets, and resiliem means carried within the said hollow binding posts ior tolcing the compressor plate against theA pack ot inserted sheets to normally maintain the pack in clamped position vcithin the binder.
